Editor’s observe: This put up is a part of our weekly Within the NVIDIA Studio collection, which celebrates featured artists, provides artistic suggestions and methods, and demonstrates how NVIDIA Studio expertise improves artistic workflows.
It’s the season of gratitude: that point of 12 months to offer thanks for the individuals and small moments that make life so particular.
This week’s featured Within the NVIDIA Studio artist, Ravissen Carpenen, is serving up a feast of mouthwateringly photorealistic 3D meals renders to the dinner desk.
His delectable time-lapse movies are featured on his YouTube channel, CG Realism — offered with a facet of upbeat music and a pinch of favor.
Carpenen was considered one of a number of contributors to the food-themed Studio Standout video contest, alongside Roger Roque (@rogerroqueid), Nicole Morena (@nicky.blender), Heloise Cart (@isoheell) and Kris Theroin (@kristheorin).
Lastly, livestreamers utilizing OBS Studio — a free, open-source software program for video recording and livestreaming — can obtain the newest replace with HDR10 seize help, WHIP and WebRTC output and extra. Be taught extra particulars.
All About That Baste
Carpenen’s spouse, a pastry chef, impressed his photorealistic, food-centered works.
“My goal, at some point, is to have the ability to create ultra-realistic renders that will likely be utilized in movie and films,” he stated.
His initiatives start with on-line analysis and reference gathering, primarily on Pinterest and Behance, which he then compiles into temper boards utilizing the stand-alone picture monitoring program PureRef.
Earlier than any modeling takes place, Carpenen lights the scene — however with out textures.
“That is to inform the story of the art work, as gentle intends to offer art work an emotional stream, alongside in addition to shade and supplies,” he stated.
Carpenen initially sculpts his fashions in ZBrush utilizing customizable brushes to form, texture and paint his digital clay in a real-time atmosphere with on the spot suggestions.
He then browses the Quixel Megascans library for fashions that may additional add realism, akin to garlic cloves and rosemary garnishes for his turkey undertaking.
Uncommon-in for Extra
Carpenen makes use of Marmoset Toolbag’s ambient occlusion, curvature, regular and thickness options to bake the ZBrush meshes from high-poly to low-poly fashions as 32-bit textures.
The method saves reminiscence area, minimizing lag time whereas permitting higher flexibility within the modeling stage.
Carpenen’s GeForce RTX 3070 GPU-powered system with RTX acceleration immediately optimized his meshes. RTX-accelerated ray tracing and OptiX AI-powered denoising additionally enabled smoother viewport motion.
Baking a Berry Good Pie
As soon as the renders are prepared, Carpenen imports them into Adobe Substance 3D Painter to use customized colours and textures.
There, Carpenen makes use of RTX-accelerated gentle and ambient occlusion baking — although not within the oven — to optimize his belongings, akin to this berry pie, in mere seconds.
He additionally had the choice to arrange a stay hyperlink connection between 3D Painter and NVIDIA Omniverse, a improvement platform for connecting and constructing Common Scene Description (OpenUSD)-based instruments and functions, by way of the USD Composer basis app.
The connection would enable Carpenen’s texture work in Substance 3D Painter to immediately translate to USD Composer — eliminating the necessity for quite a few file imports, exports and reformatting.
Donut Gap in One
Carpenen makes use of Blender to carry his scenes along with superior mannequin sculpting, animations and additional lighting refinement.
RTX GPUs enable smoother motion within the viewport because of Blender Cycles’ RTX-accelerated OptiX ray tracing.
And for exporting closing information, RTX-accelerated OptiX ray tracing in Blender Cycles delivers the quickest final-frame render.
Due to AI, This Work Is Toast
Carpenen makes use of Adobe Photoshop Lightroom to place the ending touches on his meals scenes.
GPU-accelerated picture processing allows dramatically extra responsive changes on his 4K-resolution show.
Carpenen had much more RTX-accelerated AI instruments at his disposal in Lightroom. The “Uncooked Particulars” function refines the high quality shade particulars of high-resolution RAW photographs. And “Tremendous Decision” makes use of AI to upscale photographs with greater high quality than conventional strategies.
In keeping with Carpenen, placing within the work is vital.
“It’s equal to training soccer — when you don’t get sufficient time each day to observe, you may’t hone abilities,” he stated. “It’s essential to know how you can sort out obstacles — and that data can solely be gained by expertise.”
